Patent GB-615523-A (GB)
Title: Improvements in method for the preparation of 1:3-diketones
IPC: C07C49/76
Filed: 1945-06-07
Abstract: Beta-diketones are produced from enol esters isomeric therewith by heating a carboxylic acyl ester of the enolic form of a ketone, which ketone contains not more than twelve carbon atoms, to a temperature between 300 DEG  and 700 DEG  C., whereby the acyl group of said acyl ester migrates to form a diketone having two carbonyl groups attached to the same aliphatic carbon atom.  Enol esters which may be isomerized to the corresponding 1,3-diketones include the acetic acid esters of the enol form of: acetone, methyl ethyl ketone, methyl propyl (butyl, pentyl or hexyl) ketones, methyl heptyl (octyl, nonyl or decyl) ketones, diethyl ketone, ethyl propyl (butyl, pentyl or hexyl) ketones, ethyl heptyl ketones, dipropyl ketones, propyl butyl (pentyl or hexyl) ketones, dibutyl ketones, butyl pentyl ketones, dipentyl ketones, methyl (or ethyl) cyclohexyl ketone, propyl cyclohexyl ketones, cyclohexyl acetone, cyclohexanone, methyl (or ethyl) cyclohexanones, propyl (or butyl) cyclohexanones, acetophenone, tolyl methyl ketones, benzyl methyl ketone.  In addition to the acetic acid esters there may be used the enol esters of propionic acid and higher homologous acids including nonanoic and decanoic acids; benzoic acid, toluic acids, phenyl acetic acid, phenyl butyric acids, dimethyl benzoic acids, hexahydrobenzoic acid, hexahydrotoluic acids.  The acyl group of the acyl ester preferably contains not more than twelve carbon atoms.  The vapours of the enol ester may be passed through a heated tube fitted with a vaporizer, preheater and condenser.  The tube may be constructed of chrome iron, silica or other material resistant to the corrosive action of the diketone produced and may be packed with an inert material.  Examples describe the conversion, generally by heating at 500 DEG  C. of: (1) isopropenyl acetate to acetyl acetone; (2) alpha-acetoxystyrene (obtained by reacting ketene with acetophenone) to benzoyl acetone; (3) isopropenyl 2-ethyl hexanoate to 2-ethyl hexanoyl acetone; (4) acetoxycyclohexene (made by the reaction of ketene with cyclohexanone) to ortho-acetyl cyclohexanone; (5) the enol-acetate of 5-ethyl heptanone-2 (made by the reaction of ketene with the ketone) to 7-ethyl nonanedione-2,4.  The enol ester starting materials may be obtained as in Specification 615,521 by acylating a ketone with a carboxylic acid ester of the enol form of a different ketone, e.g. by using an enol ester such as isopropenyl acetate as the acylating agent for reaction with a ketone other than acetone.

Title: A device for ascertaining the end of printing in a high-speed printing mechanism
IPC: G06K15/08
Filed: 1963-04-11
Abstract: 1,038,503. Electric selective signalling systems. OLYMPIA WERKE A.G. April 11, 1963 [May 24, 1962], No. 14555/63. Heading G4H. A high-speed printer receiving data from a store is characterized in that means are provided for producing an " end of print " signal when the store is empty. This feature permits a further print cycle to be initiated immediately the store is empty without waiting until the end of a fixed-length print cycle and eliminates " dead " time. As described the store is a matrix of cores or gas tubes and its condition is detected either by having a Hall generator (Fig. 7, not shown) in each core, the Hall generators being connected in parallel, or by having a single photo-cell 51, Fig. 5, which will detect if any tube is glowing. If print-hammers of the kind that have to be pre-tensioned are used before printing are employed these can be used to provide a signal when they have all returned to their normal positions. Thus in Figs. 3 and 4 those print hammers 61 or 612 corresponding to columns of the matrix storing data are displaced resulting either in the opening of a contact 515, Fig. 3, or the blocking of a light beam 67, Fig. 4, until all the hammers return to their normal position. In the printing system described data is read into the store under the control of a counter 11, Fig. 5, and is then read out by successive diagonals, under the control of clock pulses 40 produced by the moving type and a rotary switch 49. When the store is empty a pulse from the photo-cell 51 passes via a gate 50 to a control unit 14 and via a lead 27 to cause the next line of data to be read into the store. When the next line of data has been entered into the store a trigger 31 is turned on and when paper-feeding has completed a trigger 32 is turned. The next clock pulse 40 from the moving type then turns on a trigger 43 via a gate 35 to start the next print cycle.
Patent GB-582643-A (GB)
Title: Improvements in or relating to spring operating-mechanism for electric switchgear
IPC: H01H3/30
Filed: 1944-07-31
Abstract: 582,643. Automatic circuit-breakers. REYROLLE & CO., Ltd., A., ALLAN, A., and SMALL, J. F. S. July 31, 1944, No. 14568. [Class 38 (v)] In an operating mechanism for an electric switch, energy is stored in a spring system, charged by moving against it two elements of a differential device, which are trigger released in turn to open or close the contacts by movement of members then set in motion by the third element. An operating lever A pivoted at A<2> is moved to the left by the anti-clockwise rotation of a spindle H carrying a D-shaped lug H' within a slot A' in the lever A. This movement tensions a spring D, rotates a lever C, and causes a forked link F to over-set a toggle G. As the lug H<1> re-enters the semi-circular portion of the slot A' the lever A is released and the spring D acting through the system A...C. rotates a bellcrank E<1>, E<2> and lifts a rod E to close the switch. Breaking the toggle G releases the pin C<1> and allows the spring D to open the switch. In a modification, Fig. 6 (not shown), the lever A is connected by a normally-overset toggle to a hooked operating lever, and released by breaking of the toggle after a predetermined movement of the lever. In a further modification, Fig. 7 (not shown), the lever A is retained by a toggle which is released when the spring is required to operate the switch initially. In Fig. 9 the first movement of the switch occurs when a toggle E' is broken and a bell-crank E<1>, E<2> thereby enabled to rotate, actuated by a compression spring D or, Fig. 8 (not shown) by a tension spring. The switch contacts may, alternatively, be coupled to one end element C<1>, of the differential device C, Fig. 16, the other two elements being urged the same way by the spring D. In Fig. 10 the single-phase automatic-reclosing circuit-breaker is closed initially by moving a lever A<5> to the right, thus setting a toggle M, tensioning the spring D, and then releasing a detent P<3> coupled to A<5> so that a spring P<4> breaks an over-set toggle P. This releases an under-set toggle S enabling the spring D to close the breaker by means of a rod E driven through differential levers C, N connected by a bell-crank C' and a link C<5>. A fault current in the phase energizes a coil Q to rotate a lever Q<1> clockwise, further tensioning the spring D, resetting the toggle P, and raising it until toggle 5 is reset. The toggle extension P<1> at this point strikes a fixed stop (not shown) and the toggle is thus broken and the spring D rotates lever N about the set toggle S and reopens the circuit-breaker. The coil Q is thus de-energized and thereby resets the toggle P, so tripping S to produce a further reclosure by spring D. Opening and closing is repeated until the fault is cleared or a timing device trips the toggles M in all phases to cause final opening by lifting the slotted link A<6>.
